Specification of Letters Patent. Patented April 7, 1908.

Application filed March 16, 1907. Serial No. 362,531.

reference indicate like parts in all of the figures, 1 designates the saw blade which is provided with a series of tooth receivin ortions 1', cut in the under side of the blade,

having their sides 1 converging'upwardly and provided with tongues 1, as shown.

My invention-relates to certain new and e upper bounding surfaces of the tooth usef improvements in stone sawing ma- ,receiving pockets 1 may be provided with chines of the removable tooth type and in tongues 1", if desired.

pockets formed in the saw tooth receiving spaces 1, countersunk into the 1 designates blade adjacent the which pockets 1 are saw blade a depth sufficient to receive the securing clips 3, which clips 3 are of substantially U-shape in cross section, and are preferably formed of spring steel or other suitable material, and when the clips 3 are in the pockets I they snugly fit the same.

portions, for locking the teeth.

11 its more detail nature, my invention embodies a locking clip, preferably of spring steel or the like, which is adapted to interlock with the saw blade and with the tooth when the tooth is inserted in the blade to prevent the tooth dropping off the blade as the saw is being raised from the cut, or when-the tooth moves out of contact with the stone during the sawing operation, as is sometimes done by tlm end tooth of. the blade.

Primarily, my invention has for its object to' provide'a saw blade constructed along the lines hereinbefore indicated, of a very and effective construction, which can be easily manufactured, and which will readily and effectively serve its intended purposes, and in its specific nature, the invention embodies certain novel de ails of construction,

arrangement and comb1nat1on of parts, all of for a purpose which will slightly upward and the saw blade may appear.

The teeth 2 may be of any desired type may be provided with spond with and interlock with the tongues on the saw blade.

The edge of the tooth which hes adjacent the'pockets 1 when in the saw blade, 1s provided with a notch 2", whose face may be provided with a groove 2, if desired, the notch 2 serving to receive the edge 3 of the clip 3 whose sides 3 are adapted to he in the ockets 1 when the tooth is locked in the blade. In inserting the tooth into the blade,- the clip 3 is first shoved into the position shown in Fig. 2, so that its sides or win s 3 will be spread and so that its edge 33* Wi lie parallel and close u to the edge 1 of the then be specifically pointed out in the ap pended claims, and illustrated in the accompanying drawings, in which igure 1, is a perspective viewof a saw blade showing my invention Fig. 3, is a similar view showing the tooth inserted. Fig. 4;, is a view similar to Fig. 8, after the clip has been moved into its pocket to lock the tooth to the blade. ig. 5, is a horizontal section on the line 55 of Fig. 3. Fig. 6, is a horizontal section on the line 66 of Fi 4. Fig. '7, is a perspective viewof one of t e teeth. Fig. 8, is aperspective view of one of the securing clips. Fig. 9, is a section on the line 99 of Fig. 3. Fig. 10, is a detail side view of a portion of the saw blade.

From the fore oing description taken in connection with the accompanying drawings,

teeth and resting in said recesses for locking the teeth in the saw blade.

2. A saw blade having tooth receivin spaces and teeth adapted to be held in said spaces, said saw blade having recesses in its SlClB faces merging with said tooth receiving s aces, combined with a locking clip removalil held on the saw blade and adapted to em race the sides thereof and engage a notch in the tooth to lock the teeth to the blade, substantially as shown and described.

3. A saw blade having tooth receiving cutaway portions Whose side walls converge upwardly, saw teeth held in said cut-away portions, said teeth having notches and said saw blade having recesses in its side faces and U-shaped clips held over said blades in said recesses to lock in the notches of the teeth.

4. A saw blade having tooth receiving cutaway portions, saw teeth held in said cutport1ons,-

saw teeth having notches combined away portions, said saw teeth having notches, said blade having recesses in its cut-away edge and in its side faces adjacent said cut away portions, and spring metal clips bent over said saw blade in sald recesses to lock in the notches of the teeth.

5. A saw blade having tooth receiving cutaway portions, saw teeth held therein, said saw teeth having notches combined with U shaped spring metal clips held over said saw blades and embracing the sides thereof, and cooperatively locking in the notches of the teeth, substantially as shown and described.

.6. A saw blade having tooth receiving cutaway portions, saw teeth held therein, said saw teeth having notches combined with U shaped spring metal clips held over said saw blades and embracing the sides thereof and cooperatively looking in the notches of the teeth, said saw blade having recessed portions on its side face to be engaged by said oh s when in their locking position, substantia ly as shown and described.

7. A saw blade having tooth receiving cutaway portions, saw teeth held therein, said with U shaped spring metal clips and cooperatively lockin in the notches of the teeth, said saw blade aving recessed portions on its side face to be engaged by said clips when in their locking position, and having a supplemental notched portion to receive said spring metal clip in its unlocked position substantially as shown and described.
